Claims.

This invention relates to a means whereby samples of rosin can beremovedreadily from barrels.

Heretofore 'it has beenl thepractice to insert into a barrel through ahole therein, a plug. having a coil attached to it within which is helda box into which the rosin will flow during the lling of the barrel. Thestaves of the barrel are generally formed of green lumber. Consequentlythe moisture therein has been Vaporized by the hot rosin and entered thesampler box or cube, where it has mixed with the rosin and discolored itso as to render it unfit as a sample.

Furthermore, as the boxv or cube has been held close to the metal plugand Within the opening in the barrel, the rosin, after hardening in thebox or cube, has become very brittle with the result that when it hasbeen removed, the sample frequently is cracked to such an extent. thatit cannot be used, for grading. This objectionable feature is presentgenerally in cold weather when the plug and the parts joined theretobecome greatly chilled.

The sampling means heretofore used and employing a coil, has beenobjectionable also because when remo-ving the same from the barrel thecoil frequently has become caught and entangled with the frazzlings atthe edge ofthe Wall of the opening so as to make it diicult and at timesimpossible to remove a useable sample.

An object of the present invention is to provide a sampler which doesnot have the objectionable features heretofore enumerated but protectsthe sample from moisture and consequent discolora tion, prevents it frombecoming brittle and cracked as a result of chilling, and insures easyremval whenever desired and without interference.

With the foregoing and other objects in View which will appear asl thedescription proceeds, the invention consists of certain novel details ofconstruction and combinations of' parts hereinafter more fully describedand pointed out in the claims, it being understood that changes may bemade in the construction and arrangement of parts Without departing fromthe spirit of the invention as claimed.

In the accompanying drawing the preferred form of the invention has beenshown.

In said drawing- Figure 1 is a section through a portion of a lledbarrel showingthe present invention in position.

Figure 2 is a front elevation o-f the structure shown in Figure l.

1936, Serial No. 71,329

Figure 3 is a View partly in elevation and partly in section showingsome of the parts of the sampler separated.

Figure 4 is an elevation of the outer end of the coil and its contents.

Figure 5 is an inner end elevation of the coil and itsI contents.

Referring to the figures by characters of reference, A designates a.portion of a wooden barrel provided with a hole B adapted to receive thesampler constituting the present invention.

The sampler includes a metal tube I which is fitted snugly in opening Band has its inner end inturned to provide a narrow flange or seat 2.Ears 3 are formed in opposed` portions of the tube near its other end.

Removably mounted in the tube l is a coiled wire 4 the ends of which areextended across the ends of the space dened by the coil, the two endsbeing indicated at 5 and 6 respectively. A box or cube l formed of sheetmetal and'having one o-r more openings 8 is removably seated in the coiland is held pressed back against the inner terminal 6 of the coil by aspacer 9 which can be in the form of a metal strip bent to form asubstantially rectangular member which is interposed between cube l andthe other terminal 5 of the coil. The inner end of the coil is heldagainst or close to ange or seat 2 by a circular plug l0 fitted snuglyin the outer end portion of tube l and bearing against the adjacent endof coil 4. This plug has openings Il through which ears 3 can be bent asshown in Figures l and 2, thus to hold the parts assembled. An annularflange l2 is formed on the plug and bears against the outer surface ofthe barrel.

After the sampler has been placed in the barrel, hot rosin C is pouredinto the barrel and will flow into tube I and fill coil 4, a sample ofthe rosin entering and filling the box or cube l.

Tube l acts as a shield and protects the contents of box or cube 'l frommoisture driven out of the barrel staves by the hot rosin. Thus thesample contained in the bdx will not become discolored. As the box orcube is held back from the plug I0, excessive cold will not be conductedthereto from the plug and consequently the hardened sample in the boxWill not become brittle and cracked. As the tube extends through openingB is constitutes a guide for the coil and permits it to be pulled outwithout diilculty. After the sample has been removed, the plug I0 can bereplaced in the tube and again fastened by means of ears 3.

What is claimed is:

l. A sampler including a tubular shield open at its ends, one of saidends being insertable into an opening in a barrel for snug engagementtherewith, thereby to be supported rigidly within the barrel, a coilremovably mounted in the shield and supported and guided thereby, a boxin the coil, and a closure for the outer end of the shield.

2. A sampler including a tubular shield having an open outer and innerend, said outer end being proportioned for snug seating within anopening in a barrel thereby to be supported rigidly within the barrel, aseat at the inner end of the shield, a closure at the outer end, a coilremovably mounted between the seat and closure and supported and guidedby the shield, and a box within the coil.

3. A sampler including a tubular Shield open at its outer and inner end,said outer end being proportioned for snug seating in an opening in abarrel thereby to support the shield rigidly withimperforate shield openat its inner and outer ends, said outer end being fitted snugly withinthe opening thereby to support the sampler rigidly within the barrel, aclosure removably seated in the outer end, means on the shieldcooperating with the closure tol hold it detachably in position, a coilremovably mounted in the shield and having terminals extendingthereacross, and a box within the coil and retained by the terminals.

5. A sampler including a tubular imperforate shield open at its innerandrouter ends, the outer end of the shield being proportioned to engagesnugly within an opening in a rosin containing barrel thereby to supportthe shield rigidly within the barrel and in position to shed moisturedirected onto the shield from the wall of the barrel, said shield havinga seat at its inner end, a closure detachably' connected to its outerend,

A a coil separate from the closure and interposed between'said closureand the seat, said coil being removable from the shield when the closureis removed, there being terminals on the coil eX- tending thereacross, abox removably mounted n the coil, and spacing means interposed betweenthe box and one terminal for holding the box adjacent to the otherterminal.
